%X Through large amount of experiments,the geometrically matched parameters in torch- set up of DE-GMAW(double electrode-gas metal arc welding)were found,and the welding current waveforms,images of metal transfer,and photographs of weld without defects were obtained.Based on these test results,the reasons that DE-GMAW can realize high-speed welding were explained.A finite-element analysis model suitable to DE-GMAW process is developed to simulate the temperature field and stress-strain field.The predicted and measured weld dimensions at cross section matched well,and the weld dimension,heat-affected zone width,stress,strain and deformation in DE-GMAW are much lower than those in conventional GMAW under same welding condition.It provides the basic data for optimizing the process parameters in DE-GMAW.
